Abstract: An anti-static compressed air filter is a needled felt made of acrylonitrile polymer fibres coated with metal for electrical conductivity; the filter is made in conventional manner. Method eliminates problems of separation of metal filaments or of hydrolysis of the organic fibres. In an example, polyacrylic nitrile staple fibres, dtex 7.8/80 mm. were dipped in a bath of HCl (pH is not >1) of colloidal palladium soln. to DT-AS 11 97 720. After stirring between 30 secs. and 2 mins. they are removed and washed with water, then dipped in 5% NaOH at room temp. for 30 secs. - 2 mins., removed and washed with water. They are placed in a solution of 0.2 mol./l. Ni-II-chloride, 0.9 mol./l. NH4OH, 0.2 mol./l. sodium hypophosphite and NH3 is passed in until the pH is 8.9-9.6 at 30 degrees C. Fibres begin to discolour after 15 secs.; after 30 secs. they are coated with fine nickel, after 5 mins. the nickel coating is 0.2um. Fibres are then removed and washed with water. Surface resistivity now 3 x 10 ohms. at 23 degrees C. and 50% R.H. according to DIN 54 345. Volume resistivity is 3 x 102 ohm.cm.2.

Title: Pastry tester using probe - measures resistance or capacitance of sample to assess quality of baking
Inventor: GRIEBEL ROBERT
IPC: G01N33/10
Filed: 1978-07-17
Abstract: The pastry tester indicates the condition of pastry during baking. A rod consisting of a central conductor is an insulating sleeve which is in turn surrounded by an outer conductor is inserted in the pastry. The two conductors are connected to an ohmmeter.

Title: Low cost TV tuner - has diode switching of LC components in oscillator and input circuits for dual band selection
Inventor: KUPFER KARL-HEINZ
IPC: H03J5/24
Filed: 1978-11-13
Abstract: Circuitry provides frequency matching and frequency dependent switching and amplifying sections of the tuning circuits in a t.v. receiver. The circuit uses switching diodes to establish and disconnect by-pass and parallel paths through out the tuner circuit. The tuner circuit is divided into various frequency dependent areas associated with Band I or Band III t.v. reception and each is fed to a separate output. The conditions applied to the mixer transistor and associated switching diodes determine whether the coils for band I or band III are connected in circuit. These coils are operated in conjunction with input circuit tuned circuits which are switched by diodes to select the appropriate output. The local oscillator is similarly controlled by two diodes in the emitter and collector circuits.
